SCP-693 is a series of 18 cm humanoid dolls, each one made from a single strand of string, with beads of onyx for eyes. SCP 693 reacts as a normal string doll until such a time as a piece of hair from the head of a still living human being is placed in a loop of its string, at which point, the SCP693 doll begins to move of its own volition, portraying the current actions of whoever it is attuned to.
